BQ4050: Charger from 99% to 100%

Part Number: BQ4050

Hello Team,

It seems we set the error parameter for bq4050, we charged the Li battery to 99%, and it can not reached the 100% until half hour latter.

So , could you have any suggestion to improve this design。

Thanks！

    Hey,

    It has to deal with valid charge termination. You have RSOCL set to 1, so SOC will report 99% until valid charge termination is reached. If this bit is set to 0, then the gauge will report 100% sooner.

    Regards,
